    (MDPI, 2024-11-22) Moya Villaescusa, María José; Sánchez Pérez, Arturo; Lara Hernández, Nerea; Jornet García, Alfonso; Montoya Carralero, José María; Dermatología, Estomatología, Radiología y Medicina Física
    Implants are increasingly used in dentistry. Nevertheless, several factors can cause treatment failure. To assess initial wound healing, various indices have been developed. The purpose of this study was to assess the relationship between early wound healing and implant success. Fifty single implants (25 in women and 25 in men) were placed in patients meeting the inclusion criteria. The implants (Ticare®) were placed via the two-stage technique. Patients were assessed at 24 h, one week, one month, and two months post-implantation. At the final evaluation, implantation failure or success was recorded. Postoperative pain in these patients at one week after placement was assessed with a visual analogue scale (VAS), and the Wachtel soft tissue early healing index was used to measure healing. Two months after implant placement, the success rate was 92%. No statistically significant relationship was found between the Wachtel index and short-term implant success or failure. Additionally, there was no relationship between implant success or failure and variables such as smoking, diabetes status, age, sex, or guided bone regeneration (GBR). Neither the Wachtel index nor any of the other variables studied is a predictor of early implantation success.

    Immediate implant placement in fresh alveolar sockets with a minimal split-thickness envelope flap: a randomised controlled clinical trial
    (Wiley, 2021-07-04) García-Sánchez, Rubén; Mardas, Nikos; Buti, Jacopo; Ortiz Ruiz, Antonio José; Pardo Zamora, Guillermo; Dermatología, Estomatología, Radiología y Medicina Física
    Objectives: comparing PES/WES scores, modified success rate, survival, success, buccal bone thickness and patient-reported outcomes of immediate dental implants placed in fresh alveolar sockets using a flap or a minimal split-thickness envelope flap (MSTEF). Materials and methods: Implants following random assignment into a flap or MSTEF group were placed immediately in anterior and premolar areas. Guided bone regeneration and autogenous connective tissue graft were used in all cases. A temporary prosthesis was provided followed by the final prosthesis at 16–18 weeks. Success and survival rates together with radiographic buccal bone thickness and patient satisfaction were evaluated at 12-month post-loading. The aesthetic outcome was evaluated through the Pink (PES) and White (WES) Aesthetic Score by 8 blind clinicians of different training background and incorporated in modified success criteria. Results: 28 implants were placed on 28 patients. No statistically significant differences were noted in PES (10.54 control versus 10.80 test), WES scores (6.97 control versus 6.95 test) or success criteria including aesthetic parameters (modified success criteria) for the different specialty groups (Range 69%-92%). In addition, no statistically significant differences were noted in survival (100%), success (100%), buccal wall thickness between control (0.72 ± 0.22) and test group (0.92 ± 0.31) and patients’ reported outcomes. Conclusions: Immediate dental implant treatment with flap/ MSTEF provided similar mean PES/WES scores, modified success rate, survival, mean buccal bone levels and patients’ satisfaction. However, aesthetic failures were common in both groups.

    Influence of the number of microthreads on marginal bone loss: a five-year retrospective clinical study in humans
    (MDPI, 2023-03-20) Jornet García, Alfonso Felipe; Sánchez Pérez, Arturo Joaquín; Planes Nicolás, Pablo; Montoya Carralero, José María; Moya Villaescusa, María José; Dermatología, Estomatología, Radiología y Medicina Física
    The purpose of the present study was to evaluate the clinical and radiographic outcomes of the number of microthreads on marginal bone over 5 years. Thirty-two implants were placed in 32 patients with partially edentulous maxillae or mandibles. Two implants with the same characteristics were placed: the first one had a 1 mm crest module and 3 microthreads (Q); and the second one had a 3 mm crest module and nine microthreads (S). The prosthesis was inserted 3 months after implant placement. Clinical and radiographic examinations were performed at the one-week, one-month, and three-month follow-up visits and then every six months until a five-year follow-up period was completed. After 5 years of follow-up, five patients withdrew from the study. Complete data were available for 27 implants, with a 100% implant survival rate. No cases of peri-implantitis were diagnosed. The average bone loss was 0.65 mm (C.I. 0.21–1.09) for Q implants and 0.86 mm (C.I. 0.39–1.33) for S implants, with no statistically significant difference. The bone level does not vary between implants with three and nine microthreads or with a 1 mm and 3 mm crest module. No differences in clinical parameters were found.

    Laterally rotated flap for soft tissue augmentation around maxillary loaded osseointegrated dental implants: preliminary results of a pilot study
    (SpringerOpen, 2021-09-09) Moreno Rodríguez, Jose Antonio; Guerrero Gironés, Julia; Pecci Lloret, Miguel R.; Ortiz Ruiz, Antonio José; Dermatología, Estomatología, Radiología y Medicina Física
    A minimal width and thickness of keratinized and attached soft tissue is desirable to prevent peri-implant diseases. This report describes the preliminary results of a pilot study of a surgical approach for soft tissue augmentation around loaded dental implants in the partially or totally edentulous maxilla. Four patients presenting eight maxillary implants with a buccal peri-implant soft tissue deficiency received a laterally rotated flap. A buccal mesial and apical recipient area was created around each implant, and a pediculated keratinized graft was rotated 90° from the distopalatal and positioned and sutured on the peri-implant buccal aspect. All implants treated showed a gain in buccal clinical peri-implant attachment (1.37 ± 0.44 mm) and buccal soft tissue levels (2.06 ± 1.40 mm) and interproximal soft tissue levels (1 ± 0.75 mm). The technique provided quality soft tissue with a gain in soft tissue thickness (3.06 ± 0.68 mm) and keratinized wide tissue (4.69 ± 0.80 mm) with minimal morbidity (1575 ± 549.67 mg of ibuprofen) and maintenance of prosthetic loading. Peri-implant soft tissue stability was maintained for 13.5 ± 1.87 months. Laterally rotated flap can be applied and provide clinical benefits to compromised implants due to the presence of buccal peri-implant soft tissue deficiency. Further studies are required to confirm these preliminary results.

    Oral surgery considerations in patients at high-risk of complications related to drug intake: A systematic review
    (Elsevier, 2024-12-02) Morgado Sevillano, D.; Rodríguez Molinero, J.; García Bravo, C.; Peña Cardelles, J.F.; Ruiz Roca, Juan Antonio; Dermatología, Estomatología, Radiología y Medicina Física
    Purpose: This study aims to identify and comprehend the management of the most frequent complications in oral surgery that arise from the consumption of multiple drugs. Materials and Methods: A comprehensive review of 23 articles was conducted, focusing on the complications that arise from the consumption of drugs in patients undergoing oral surgery treatment, in addition to the strategies for prevention and treatment. Results: All the reviewed articles offered insightful knowledge into preventing complications through welldefined protocols that encompass both pre- and post-operative measures. These measures include local interventions such as periodontal treatments, dental prophylaxis, and hygiene instructions, as well as systemic approaches like antibiotic prophylaxis and post-surgical antibiotic coverage. Additionally, specific measures like monitoring prothrombin time with the International Normalized Ratio in patients with coagulation disorders, and implementing hemostatic techniques, were also discussed. onclusion: The most prevalent complications in oral surgery are hemorrhage in anticoagulated patients, infections in immunosuppressed patients, and osteonecrosis in patients who take antiresorptive drugs. Edema, pain, and inflammation are also common post-operative concerns. When managing high-risk patients pharmacologically, it is crucial to provide effective antibiotic coverage both pre- and post-procedure and to utilize minimally invasive dental procedures with local hemostatic measures.

    Valor pronóstico de la densidad ósea y de la movilidad en el éxito implantológico
    (Sociedad Española de Cirugía Oral y Maxilofacial (SECOM), 2017) Moya Villaescusa, María José; Sánchez Pérez, Arturo Joaquín; Dermatología, Estomatología, Radiología y Medicina Física
    Objetivos: Evaluar el valor pronóstico de la movilidad primaria (momento de inserción del implante) y secundaria (fase protésica), así como el de la densidad ósea en el resultado de éxito o fracaso del implante durante un seguimiento continuado al año, a los 5 años y a los 10 años. Material y métodos: Se realizó un estudio longitudinal prospectivo con un seguimiento a 10 años en el que se incluyeron 151 implantes colocados en 71 pacientes, no fumadores, durante los años 2005 y 2006. A cada uno de los implantes se les midió las estabilidades primaria y secundaria a través de un valor Periotest® (VPT) y se anotó la densidad ósea presente en el momento de la implantación. De los 151 implantes colocados inicialmente, completaron el estudio 109. Resultados: No se observaron diferencias estadísticamente significativas respecto a la movilidad del implante en el momento de inserción o en la fase protésica y el éxito o fracaso del mismo al año, a los 5 años, o transcurridos 10 años desde su inserción. Sí encontramos diferencias estadísticamente significativas con relación al tipo de densidad ósea donde se colocó el implante a los 5 y 10 años (p < 0,05). Conclusiones: La movilidad primaria o secundaria del implante carece de valor pronóstico significativo sobre el éxito del mismo transcurridos 10 años desde su inserción. Por el contrario, la densidad de hueso inicial tiene una clara influencia en el éxito del implante a los 10 años, siendo más proclives al fracaso los huesos de alta densidad ósea. ----------------
